The Diversity of Parasitoids and Their Role in the Control of the Siberian Moth, (Lepidoptera: Lasiocampidae), a Major Coniferous Pest in Northern Asia.

The Siberian moth, Tschetv., 1908 (Lepidoptera: Lasiocampidae) is a conifer pest that causes unprecedented forest mortality in Northern Asia, leading to enormous ecological and economic losses. This is the first study summarizing data on the parasitoid diversity and parasitism of this pest over the last 118 years (1905-2022).

Varietal Differences in Juice, Pomace and Root Biochemical Characteristics of Four Rhubarb ( L.) Cultivars.

The complex evaluation of varietal biochemical differences in rhubarb juice, pomace and roots is highly useful to develop an efficient processing technology. Research was carried out to compare four rhubarb cultivars (Malakhit, Krupnochereshkovy, Upryamets and Zaryanka) in terms of the quality and antioxidant parameters of juice, pomace and roots. The laboratory analyses showed a high juice yield (75-82%) with a relatively high content of ascorbic acid (125-164 mg L) and other organic acids (16-21 g L).

[Influence of multiple insufficiency of vitamin D and B group vitamins, calcium and magnesium in the diet of rats on micronutrient sufficiency and plasma biochemical indicators].

The lack of vitamins D, B group, calcium and magnesium is common for the diet of the Russian population. It has been previously demonstrated that that the elimination of B vitamin deficiency is a necessary condition for the implementation of vitamin D biological functions. of the research was to assess the effect of a combined deficiency of vitamins D and B group, calcium and magnesium in the diet of rats on biomarkers of micronutrient sufficiency and plasma biochemical indicators.

[Vitamin supply of patients with type 2 diabetes mellitus complicated by nephropathy].

Insufficient vitamin content in the diet is a risk factor for the development of various diseases and their progression, and drug therapy can also contribute to the development of a deficiency of these micronutrients. Data on vitamin sufficiency of patients with type 2 diabetes mellitus (T2DM) and diabetic nephropathy (DN) are needed to develop measures to improve it. of the research was to compare vitamin status of patients with T2DM without DN and those with T2DM complicated by nephropathy by assessing vitamin blood level and urinary excretion.
